RBM3
Chr XRNA binding motif protein 3
Also known as: IS1-RNPL, RNPL
RBM3 encodes a cold-inducible RNA-binding protein that enhances global protein synthesis and reduces microRNA abundance. Mutations in this highly constrained gene (pLI 0.83, LOEUF 0.52) cause neurodevelopmental disorders, though the specific phenotypes and inheritance patterns associated with RBM3 variants are not well-established in the provided data.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Mild missense constraint
The highest-scoring mechanism for this gene is dominant-negative.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
